Input/Output
Data Connection Routines
Returns the text string associated with the negative status code generated by a “DC” data import/export function that does not complete successfully.
Sets the error message reporting level for all “DC” import/export functions.
Reads an 8-bit image file.
Reads a 24-bit image file.
Reads a single variable from an HP VEE Container file.
Reads data from a Device Independent Bitmap (DIB) format file into a variable.
Reads fixed-formatted ASCII data using a PV‑WAVE format that you specify.
Reads freely-formatted ASCII files.
Reads a Tag Image File Format (TIFF) file.
Scans an HP VEE Container file to determine the number and location of defined variables.
Writes 8-bit image data to a file.
Writes 24-bit image data to a file.
Writes image data from a variable to a Device Independent Bitmap (DIB) format file.
Writes the contents of one or more PV‑WAVE variables (in ASCII fixed format) to a file using a format that you specify.
Writes the contents of one or more PV‑WAVE variables to a file in ASCII free format.
Writes image data to a file using the Tag Image File Format (TIFF) format.
Input and Output Routines
Associates an array structure with a file, allowing random access input and output.
Converts integers between host and network byte ordering. Can also be used to swap the order of bytes within both short and long integers.
Reverse the byte order for each element of an array.
Returns the next character available from standard input (PV‑WAVE file unit 0).
Standard Library procedure that opens or closes an output file for LN03 graphics output. The file can then be printed on an LN03 printer.
PRINT performs output to the standard output stream (PV‑WAVE file unit –1).
PRINTF requires the output file unit to be specified.
Read input from the standard input stream into PV‑WAVE variables.
READF reads input from a file into PV‑WAVE variables.
READU reads binary (unformatted) input from a specified file. (No processing of any kind is done to the data.)
READU_32 reads a long data type as a 4-byte value from the given input stream. It is useful in reading 32-bit Longs on a 64-bit system. In addition, it can be used to read any other PV‑WAVE data types.
Reads in hourly data from a file in the AIRS (Aerometric Information Retrieval System) format.
(Microsoft Windows Only) Prints the contents of a specified window.
(Microsoft Windows Only) Loads a Device Independent Bitmap (DIB) from a file into a graphics window.
(Microsoft Windows Only) Loads a Windows metafile (WMF) into a graphics window.
Writes binary (unformatted) data from an expression into a file.
(Microsoft Windows Only) Saves the contents of a graphics window to a file as a Device Independent Bitmap (DIB).
(Microsoft Windows Only) Saves the contents of a graphics window to a file as a Windows metafile (WMF).
