[Solution] VeryPDF Text to PDF Converter: The Complete Solution for Converting ASA-Controlled Text Reports to PDF

In today’s digital business environment, accurate and professional reporting is essential. Many organizations still rely on legacy mainframe systems that output reports in plain text formats. While these text files are lightweight and easy to generate, they often use ASA control characters, which are special formatting instructions designed for line printers. Converting these files into modern PDF documents while preserving formatting, page breaks, and overprint instructions can be challenging.

VeryPDF provides a robust solution for converting text reports containing ASA control characters into PDF files, preserving the original formatting and enabling customization such as font size, line spacing, margins, and page orientation. This ensures that even legacy reports can be shared, printed, or archived professionally.

Understanding ASA Control Characters

ASA control characters originated in IBM mainframe environments and were used to control line formatting and page layout on line printers. These characters are placed at the very beginning of each line in a text report and include:

“+” (Overprint): Combines the current line with the previous line without advancing the paper.
“0” (Single blank line): Inserts a single blank line in the output.
“-” (Double blank line): Inserts two blank lines.
“1” (New page): Starts a new page in the report.

Example of ASA-Controlled Text Report

1Report Title
+Subtitle
0
0Date: 2026-03-31
-
Employee Name Hours Worked Salary
+--------------- ------------- ---------
John Doe 40 1200
Jane Smith 38 1140
1Page Summary
+Total Employees: 2

In this example:

The “1” at the beginning of “Report Title” starts a new page.
The “+” merges the subtitle with the previous line.
“0” adds single blank lines, while “-” adds double blank lines.

Without proper handling, converting this file to PDF may result in misaligned columns, incorrect spacing, or broken page breaks, making the report unreadable or unprofessional.

Why Convert ASA Text Reports to PDF?

While text files are simple, PDFs offer numerous advantages:

Consistent Layout: PDFs preserve fonts, line spacing, and columns.
Print-Ready Format: PDFs are compatible with any printer and maintain professional formatting.
Archiving and Security: PDFs can include metadata, encryption, and watermarks.

By converting ASA-controlled reports into PDFs, organizations can modernize their reporting workflows while preserving critical legacy formatting.

2. Font and Layout Customization

Every PDF report can be tailored with:

Font Size: Adjust text size for readability.
Line Spacing: Add extra spacing between lines if needed.
Margins: Control the amount of white space around the page.
Lines per Page: Ensure that each page contains the exact number of lines desired.

Example Command-Line Usage:

text2pdf.exe input.txt output.pdf --fontsize 10 --linespacing 4 --linesperpage 60
text2pdf.exe report.txt report.pdf --margin 50 --fontsize 12

These options ensure that even very detailed reports maintain readability and proper alignment in PDF form.

3. Landscape and Portrait Orientation

Wide reports often exceed the standard portrait page width. VeryPDF allows:

Automatic landscape conversion for wide tables or reports.
Manual override using the --landscape flag.

Example:

text2pdf.exe input.txt output.pdf --landscape --fontsize 11 --linesperpage 70

This is especially useful for inventory reports, payroll reports, or shipping logs that have wide columns.

4. Command-Line Automation

VeryPDF’s CLI makes batch processing multiple reports simple. This is essential for enterprises that generate daily, weekly, or monthly reports.

Batch Example:

text2pdf.exe report1.txt report1.pdf --fontsize 10
text2pdf.exe report2.txt report2.pdf --fontsize 12 --linespacing 5
text2pdf.exe report3.txt report3.pdf --landscape --margin 60

The ability to script these commands allows integration into ERP systems or automated workflows, minimizing manual intervention.
