FILETOVAR Command

The FILETOVAR command copies data from a file and appends it to a variable level.

file-name

is the name of an existing file from which data is to be copied. It must be readable

by the sequential I/O facility (SIO). Both format1 and format 2 files are supported.

variable-level

is the name of an existing variable level to which the copied data is to be

appended. The variable must not be in a shared segment and must not be a

directory, a STRUCT, or a STRUCT item.

Considerations

Lines longer than 239 characters in the file are truncated to 239 characters when they

are appended to the variable level.

File I/O appears in PLAIN format, which means that no special interpretation is given to

the TACL metacharacters [, ], |, ==, {, and } when they are read. In particular, this

means that you cannot copy TACL statements from a file to a variable unless you

wrote the statements into the file with the VARTOFILE command originally. (When

TACL loads code from a file into a variable, it processes metacharacters to produce

executable code, but FILETOVAR only moves text into the variable.)

Another, faster way to append data to a variable level is to use the #SET command:

#SET /IN file-name/ variable

As with the FILETOVAR command, TACL INFORMAT must be set to PLAIN when

using the #SET function in this manner.
